I recently attempted to contact B&K/ATI via telephone and email regarding an older model pre pro I was experiencing problems with.

They never bothered to return my phone calls or email.

The Pro 10MC was one of B&K's best products that they produced, it is a very listenable product, most likely worth a repair if not too costly. However, it is valued in the neighborhood of $250 right now. The Classe 50, is clearly a better product, but probably worth somewhere around $500 to $800. Neither of these products are considered bright. Tobb has recommended a terrific product, but it is new, you won't find a used one for quite some time and it runs around $6500.
At under $1000, I like the Muse 3 Signature or maybe a Audio Research LS9, both are single ended and balanced, both sound near dead neutral and both have remote.
You could could try a cables or a little less tow in on your speakers or both, that would effect high end and listener fatigue.... Good Luck, Tim

Finding a Classe CP-50 for $500 is extremely optimistic, unless it is in poor condition. Those go for more like the $900 range in good working and cosmetic condition. The published Audiogon Bluebook value exceeds that amount.

Tapar1, Is your the Pro10 preamp the model with the red/blue or black/gold writing on the black faceplate or the machined black faceplate with grayish inlaid color where its sort of recessed? There were early and late generation pro10s.

Depending on which version pro10 it is, if you decide to let go of it, I might be willing to take it off of our hands if the price is right and to fund your next preamp purchase.
